In the initial state, the sliding gear 67 and the rotating gear 43 are in an engaged state, and the push plate 18 is located on the left side of the push block 17 under the action of the return spring 57.

The sequence of mechanical actions of the entire device:

1: When cosmetics are needed, the motor 71 is started, the motor 71 works to drive the transmission shaft 70 to rotate, and the transmission shaft 70 rotates to drive the sliding gear 67 to rotate, thereby driving the rotation gear 43 meshed with it to rotate, thereby driving the rotation shaft 41 and the rope The wheel 40 rotates, and the rope winding wheel 40 rotates to tighten the hemp rope 30. The baffle 24 moves upward under the pulling force of the hemp rope 30. The baffle 24 moves upward while pressing the stopper 28 to the right into the stopper cavity 26. When the lower end of the baffle 24 moves to the upper side of the stopper 28, the stopper 28 is ejected by the elastic force of the elastic spring 27 to stop the baffle 24 from moving downward to reset, and the upper end surface of the baffle 24 presses the pressure block 32 into the pressure block. In the cavity 33, the string 35 is thereby tightened, thereby opening the storage cavity 12 for storing cosmetics;

2: The string 35 is tightened, and the sliding gear 67 moves to the left under the pulling force of the string 35. The sliding gear 67 is disengaged from the rotating gear 43 and meshed with the driven gear 45, thereby driving the driven gear 45 to rotate. The driven gear 45 rotates to drive the driven shaft 37 and the second spring 38 at the left end of the driven shaft 37 to rotate, thereby driving the first spring 36 meshingly connected with the second spring 38 to rotate, thereby driving the rotating rod 56 and the rotating rod. The lower rotation gear 55 rotates, and the rotation gear 55 rotates and drives the rack 54 meshed to the left to move to the left, thereby driving the push plate 18 and the storage block 19 and the pressing rod 23 at the left end of the push plate 18 to the left, thereby accommodating the housing. The cosmetic in the cavity 20 is sent out to the left;

3: If you want to remove the cosmetics in the other two storage chambers 12, you only need to manually rotate the screw 46. When the screw 46 rotates, it pushes to the left in the threaded hole 47, thereby pushing the sliding gear 67 to the left to move to the meshing connection with the intermediate gear 62. Therefore, the distance that the screw 46 is pushed to the left is different, so that the sliding gear 67 is controlled to mesh with the intermediate gears 62 on the front and back sides, thereby transmitting power to the device to control the cosmetics pushing device in the different storage chambers 12;

4: When cosmetics need to be stored, simply put the cosmetics in the storage cavity 20 in the storage block 19, and then press the pressure lever 23 to the right, so as to push the storage block 19 and the push plate 18 to the right in the storage cavity 12, and push During the movement of the plate 18 to the right, the push block 17 is pressed, and the push block 17 is moved downward, so that the pull rope 14 is tightened, and the stopper 28 is pulled by the pull rope 14 to move to the right to leave the blocking baffle 24, baffle 24. The storage chamber 12 is closed by its downward movement under its own gravity. At this time, the pressing lever 23 is stopped, and the push plate 18 is moved to the left of the push block 17 by the elastic force of the reset spring 57. The push block 17 is at the spring 16 The upward movement is reset under the effect of the completion of the storage process.
